What are the main functions of the nervous system?
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
What is an example of a basic nervous system function?
The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
What are 3 functions of nervous system?
The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.
Which is the first function of the nervous system?
The process of integration combines sensory perceptions and higher cognitive functions such as memories, learning, and emotion to produce a response. The first major function of the nervous system is sensation—receiving information about the environment to gain input about what is happening outside the body (or, sometimes, within the body).
How does the nervous system control your body?
Intelligence, learning and memory: your thoughts and feelings are controlled by the brain, the control centre of the nervous system. Movement: the brain sends messages that control how your body moves. Basic body functions: the nervous system controls the things you don’t think about, like the beating of your heart, breathing, digestion.

What makes up the central nervous system ( CNS )?
your central nervous system, or CNS, which consists of the brain and spinal cord your peripheral nervous system, which consists of nerves that connect your CNS to the rest of your body Nerves are made up of cells called neurons. These carry messages from one part of the body to another. Different types of neurons do different things.
What are the functional divisions of the nervous system?
Divisions of the Nervous System. The functional divisions of the nervous system as a whole are the somatic nervous system and the autonomic nervous system. The autonomic nervous system is subdivided. Those subdivisions are the sympathetic nervous system and the parasympathetic nervous system.
What is the nervous system and its role?
Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).
What is the purpose of the nervous system in your body?
The nervous system helps all the parts of the body to communicate with each other . It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages. The basic building block of the nervous system is a nerve cell, or neurone.
What are the most common CNS disorders?
These include a group of CNS disorders which consist of: Small artery stroke, large vessels ischemia, carotid atherosclerosis, ischemic shock etc. Cerebrovascular diseases include some of the most common and devastating CNS disorders: ischemic stroke and hemorrhagic stroke.
